Circulatory System Word Search, free printable PDF preview

The circulatory system moves blood to every cell in the body. The heart has four chambers, two an atrium and two a ventricle, with a valve between them to keep flow moving one way. Blood leaves through the aorta and travels along an artery, narrowing into a capillary thin enough to reach single cells, then returns through a vein. Hemoglobin carries the oxygen and plasma carries the rest. This word puzzle gathers eleven of those parts.
